Abstract

L'invention concerne un procédé et un dispositif pour mettre en oeuvre ce dernier, servant à reconnaître et à localiser, de manière sélective, des défauts à la terre monopolaires à valeur ohmique élevée dans des réseaux de distribution électrique à compensation du neutre. Selon l'invention, au moins un signal auxiliaire présentant la fréquence de réseau φN est introduit dans le système homopolaire du réseau, en particulier de sorte que la tension de décalage du neutre Une(φN) soit ainsi pratiquement compensée à la fréquence de réseau φN. La reconnaissance et la localisation de défauts à la terre monopolaires à valeur ohmique élevée s'effectuent ainsi à la tension de décalage du neutre compensée Une(φN). L'invention concerne également un procédé permettant d'adapter la bobine de soufflage au réseau de distribution, même à une tension de décalage du neutre compensée Une(φN).
